Photographic slide mount riveting press

ABSTRACT

The present invention includes a pair of spaced apart rotatable rollers and motor means for turning one of the rollers and a guide for directing a plastic photographic slide mount between the rollers so that the pressure of the rollers against the frame members of the slide mount will deform rivots integral with one side of the slide mount frame in order to secure the two sides of the frame together.

l Claim, 4 Drawing Figures PTENTEDSEP' s len SHEE 1 0F 2 INVENTOR PTENTEDSEP' 51912 SHEET 2 0F 2 INVENTOR R L E w Y A WE K/ N R e m Y MT E A L N7 A T Y/L/ PHGTOGRAPHIC SLIDE MOUNT RIVETING PRESS The present invention relates to roller press apparatus for mounting and securing photographic transparencies in plastic mounts which are composed of opposing frame members secured together by deformable rivets.

Most prior art film mounts consist of a pair of frames, made of paper board or similar material, hinged together along one edge, and adapted to be folded together on the hinged edge with the transparency placed between the two frames so as to be visible through the registered apertures in the two frame members. Later improvements in slide mounts have been made and one type of mount is now constructed from a deformable plastic material and consists of two separate frame members which may be placed together to embrace the film transparency and which are permanently held in that position by riveting, the details of which will become more apparent as the specification proceeds.

Itis the primary objective of the present invention to provide an electrically operated automatic press which may be advantageously used to rivet the two sections of the slide mount frame together and which riveting press will maintain the frame sections tightly pressed together and against the transparency in order that misalignment will not occur during the riveting process.

Another object of the invention is to provide means and apparatus by which the riveting operation connected with slide mount assembly may proceed more rapidly and precisely than with other prior forms of riveting apparatus.

Other and further objects, features and advantages of the invention will become apparent as the description of the preferred form of the invention proceeds taken in connection with the accompanying drawings in which:

FIG. 1 is a side elevational view of the slide roller press of the present invention.

FIG. 2 is a cross-sectional view taken along lines 2-2 of FIG. 1.

FIG. 3 is a cross-sectional view taken along lines 3 3 of FIG. 2.

FIG. 4 is a top plan view of the riveting press of the present invention.

The slide mount press apparatus of the present invention is seen in FIG. 1 and is referred to generally in that Figure by reference numeral 5. A fragmented view of a photographic slide mount 7 is shown above the press in position to enter the opening 9 (see FIG. 4) in the housing 11.

Located generally below the opening 9 are a pair of rotatable rollers, l2 and 13 which are supported by a pair of opposed channels and 16. The spindles 18 and 19 of the rollers are disposed parallel to one another. The spindle 19 of the knurled roller 13 is operatively connected to an electric motor 20 through appropriate speed reduction gearing (enclosed by the housing 21). The motor 20 is controlled by a well known switch mechanism 23 through which the motor is connected to a source of electrical power.

The spindle 18 of the unpowered roller 12 is journalled on each of its ends in blocks 24 and 25 which are both slideable in the supporting channels 15 and 16.

The slidin feature of the blocks 24 and 2S is to rovide an adjusta le spacing between the periphery of ghe two rollers 12 and 13 so as to permit precise riveting of the slide mount as it progresses through the rollers. Sliding movement of the blocks is produced by rotation of the screws 27 and 28 which threadingly engage the respective blocks 24 and 25. Each of the screws is held in place by appropriate apertures in the front of the housing 1 l.

The knurled roller 13 is provided with a removeable plug device 26, one side of which forms a portion of the periphery of the roller. The periphery of the plug is provided with raised lettering or other indicia which serves to print desired information on the frame of the slide as it passes between the rollers. The raised letters are inked by ink pad 29, as is well known in the printing art.

Beneath the space between the two rollers l2 and 13 is a chute 30 into which the riveted slide mount drops after passing between the rollers. The chute 3 0 is inclined so that the slide will move downwardly and out of the opening 32 in the housing 1 1. A rack 35 having a rear hanging hook 36 is provided below the opening 32 to catch and store the finished slides.

In operation a plastic slide is inserted into the top opening 9 and is directed between the rollers by a pair of guides 37 and 38. Powered roller 13 is rotated by the motor 20 and as the plastic slide mount is drawn between the rollers the plurality of plastic rivets in the mount are deformed and upset, causing the two halves of the plastic frame to be joined together. The interspace between the rollers can be changed by adjustment of the screws 27 and 28 in order to obtain the correct amount of deformation and upset on the rivets.

I claim:

1. A photographic slide mount riveting press cornprising means for securing a photographic transparency in a mount, said mount comprised of opposing frame members secured together by deformable rivets, said means comprising in combination:

a first roller having a knurled peripheral surface;

a second roller mounted for rotation about an axis parallel with the axis of rotation of said first roller, said first and second rollers causing deformation of said rivets for securing said frame members together;

drive means connected to said first roller;
